ATTACHMENT FOR TEMPERAT`URE"INDIGATING DEVICES.

Application filed January 3Q, 1925. Serial No. 5,822.

To all whom t may concern.'

Be it known that l, Irvine FLoaMAN, a citizen of the United' States,residing at New York, inthe county of New York and State of New York,have invented a new and useful Attachment for Temperature-Iridiin thedark, especially from the drivers' seat. lt has previously been proposedto provide the indicating); dial of the device with an .opening orshutter designed to admit rays of light to the back of the thermometer,Vas viewed from the front seat of the .canin order to facilitate thereading of the thermometer, but such a provision necessarily does Vnotprove satisfactory at night due to the absence of sutlicient light.

A general object of the present invention is to provide a device whichmay be readily attached to any standard temperature indicator, wherebythe latter is illuminated in an eliicient and satisfactory manner at alltimes.

A further object of the invention yis to provide a signal device formotor vehicles adapted to display a danger or safety warning` to othervehicles to indicate the vehicle having the ri ght of way, therebyserving to reduce the number of accidents occurring at intersecting'thoroughfares.

These and other features of the invention will appear more fully fromthe following detailed description when read in connection with theaccompanaying drawings and will be pointed out in the appended claims.

In the drawings:

Figure 1 is a front view of an embodiment of the invention in positionupon a temperature indicating4 device;

Figure 2 is a side view thereof;

Figure 3 is a rear view; and

Figure l is a vertical cross section.

Referring1 more particularly to the drawings, 2 indicates the `main bodyor casing of a temperature indicating device of the type commonlyemployed upon the radiator of a motor vehicle. idlithin the casing athermometer et is arranged, the thermometer being in communication withthe inside of the adiator in such a` manner as to record the temperatureof the cooling medium therein. On the opposite side ofthe thermometerfrom the driversseat, an indicating' dial 6 is provided'havinn` indiciaupon the inner face thereof to facilitate the reading of thethermometer. The dial 6 is provided with the usual opening 7 for thepurpose of allowing` the entrance of light to illuminate the dial andthermometer. The casing 2 is closed by front and rear plates or crystals8 formed of glass or other transparent maten rials. The crystals areheld in place by annular locking' rinus 10 having suitable openingstherein for the reception of screws 12 by means of which the rings aresecured to the indicator casingzl The above mentionedgeneral features ofthe construction and operation of the temperature indicator ditl'er inno essential re-` spect from the construction and operation ofindicators of this type heretofore in use. and, since it does notconstitute an essential part of the present invention, will not befurther described in detail.

The numeral 14 indicates a casino,l adapted to be detachably connectedto the front face of the indicator inthe manner clearly illustrated inthe drawings. Thev casing- 14 may be ofV any desired shape orconfiguration, but, since it occupies a conspicuous place upon thevehicle, it is preferable Vto give the casing an ornamental appearance,such as by forming it as an animal, person, or bird, the presentembodiment illustrating the casing formed as an owls head.

The casing 14 is enclosed on all sides except the rear face, which isplaced adjacent the front face ofthe indicator. Securely mounted withinthe .casing is an electric socket 16 adapted to receive an electric bulb18. Current is supplied to the bulb by means of a suitable flexible wire20, one end of which extends through an opening` inthe bottom of thecasing, the other end being connected to the ignition system of thevehicle. rlhe bulb 18 is substantially on the level with the openingv 7in the indicator dial 6, so that rays of light from the bulb will passthrough the opening and eiiectively illuminate the therinonieter in amanner clearly understood.

The front face of the casing 14 is pi'oiided with a plura ity of spacedopenings Within which are nioiinted jewels the latter being held inposition in any suitable inanner. lroni this construction, it vill bezippiirert that light troni the bulb will be projected through thejeivels or lenses 24e i'orivard of the vehi le. li' the caising is inthe shape ot the head oi a ligure, the jewels are preferably arranged ina position corresponding' to the eyes of the iigiiie,

@n each side thereo't, the casing l; is provided with openings :ind Q7,through 'which rays of lig/'lit -troni the electric bulb 1S :ire adaptedto project on both sides of ytiie vehicle. The openings QG, 2T are coi'-ered by pri-nes or iviiidovvs ne ot lransparent material sii-li ss glassor Celluloid. Upon the inner surface of the i ig adjacent the edges oftheopenings 2G, 2.7 are oi'nied upstanding ribs or projections 30, theside of the ribs toward the openings being` undercut to provide .ideWays for retaining the iviiic-.oivs 28 in position. llroni thisconstruction, the ii'iii doivs 2S are reinoveoly retained in positionWithout the necessity of additional ina iially operable ifzisteninkineens.

l"'ilhile the Windows or panes niey be ot any desired color, it, ispreferable to have ii red ivindoiv covering the opening 26 which is tothe drirers left, and the opposite Windovv green. .By this arrangement,vehicles approaching an intersection iron ,the drivers left ivill seethe red or danger signal., which "will reinind drivers oit theapproaching vehicles Ythat the vehicle upon the rig-'ht ,has the rightol Way. Similarly, 2i 'vehicle approaching frein the right would thegreen or safety signal indicating that :ipproachine,v vehicles have theright oi? ivay.

'lhe casing lllis provided with openings Si by ineens ol Which thecasing is detachalily secured to theindicating` device through thescrews l2. Adjacent each opening` Sill, the casing` is recessed'as at Sto alioid iiccess to the screws 12.

rlhe assembly of' the casing upon the teniserted in the peningjs 3l inthe casing to 'testen 'the latter in position.
